Optimized Design and Propulsion Performance of the Robotic Sea Lion Foreflipper
ProceedingsOtariidae are the only marine mammals that use their foreflippers for propulsion, and the combination of hydrofoil and paddle propulsion makes them excellent hunters and swimmers. Therefore, it is of great scientific significance and engineering value to

Stranded Marine Mammals on the South-Central Coast of Peru during El Niño 1997-98
Revista Peruana de BiologíaDuring the 1997-98 El Niño event, an assessment of marine mammal strandings was conducted from August 1997 to April 1998 between 15°22' and 15°27' S. This assessment encompassed 30.4 km of coastline, distributed in seven sectors located along the borders

Zoology, 2019 Pinnipeds are semiaquatic carnivorans that spend most of their lives in water and use coastal terrestrial, or ice pack, environments to breed, molt and rest. Certain characteristics of the ear have been linked to ecological aspects.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans
The Anatomical Record, EarlyView.Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Phylogeographic and Demographic Analysis of the Asian Black Bear (Ursus thibetanus) Based on Mitochondrial DNA. [PDF]
, 2015 The Asian black bear Ursus thibetanus is widely distributed in Asia and is adapted to broad-leaved deciduous forests, playing an important ecological role in the natural environment. Several subspecies of U. thibetanus have been recognized, one of which,

Wildlife Letters, Volume 4, Issue 1, Page 10-22, March 2026.In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

Effect of angle on flow-induced vibrations of pinniped vibrissae. [PDF]
PLoS ONE, 2013 Two types of vibrissal surface structures, undulated and smooth, exist among pinnipeds. Most Phocidae have vibrissae with undulated surfaces, while Otariidae, Odobenidae, and a few phocid species possess vibrissae with smooth surfaces.

Improvement in survivorship: The key for population recovery? [PDF]
, 2016 In northern Patagonia, commercial harvesting of South American sea lions, Otaria flavescens, from 1920 to 1960, decimated its population abundance. Population recovery was not immediate after hunting ceased in 1962.
